...you may argue with an atheist about something such as the intricacies of an information usage, storage, retrieval, and reproducible system such as DNA. You may point out that such as system has never been seen to spontaneously appear in nature, nor gradually develop in nature, nor in laboratories. They will respond that given enough time such a system could develop. Thus, given enough time anything can happen.Materialists like to make a big deal out of making sure that statements are falsifiable. Well, is the boldfaced statement falsifiable? How?
They will also conjure a non-disprovable concept that states that since materialism is true, given enough time scientists will, no doubt, be able to explain everything by materialistic means. This means that they feel free to claim that science now means that they can believe in something for which there is no proof because they have faith that someday it will be proven true—in a year, a decade, a century, a millennia, etc.
1) it knocks down the priority of falsifiability for these types of metaphysical statements, and
2) the "God of the gaps" argument is diminished in its power.
